■Essential Question: –What were the important

contributions of Copernicus, Kepler, Galileo, & Newton during the Scientific Revolution?

■Warm-Up Question:

From 1550 to 1700, Europe experienced a Scientific Revolution when new ideas in

physics, astronomy, biology, anatomy changed the way Europeans viewed the natural world

Thinkers used logic & the scientific method to find

answers to questions

Everything was questioned & nothing

was assumed to be true

Reasons for Scientific Revolution ■The Scientific Revolution began in 1550s

because of the recent discoveries in other areas of European life: –During the

Renaissance, people began to question old beliefs & thought that humans could accomplish anything

Reasons for Scientific Revolution ■The Scientific Revolution began in 1550s

because of the recent discoveries in other areas of European life: –During the

Reformation, people began to question the ideas of the Roman Catholic Church

Reasons for Scientific Revolution ■The Scientific Revolution began in 1550s

because of the recent discoveries in other areas of European life: –In the Age of

Exploration, the discovery of new lands led people to search for other “new” things

Because of the Renaissance,

Reformation, & the Age of Exploration…

people began to question everything

“Flow Chart on Scientific Breakthroughs” –Match the cards with the appropriate

place on the flow chart –Check with the teacher when you

think you have the answers correct & then glue the cards onto the flow chart

■After the activity, use the flow chart to match the following images to the correct scientific thinker & explain why

#1 Who’s Scientific Idea?

#1 Nicolaus Copernicus ■Copernicus’ heliocentric hypothesis

proposed that the earth & other planets revolve around the sun, not around Earth

–This radically changed Europe’s concept of the universe & laid the foundation for modern astronomy

Johannes Kepler ■ Johannes Kepler mathematically proved

Copernicus’ heliocentric theory & proposed that planets move in elliptical orbits & do not always travel at same speed around the sun

#2 Who’s Scientific Idea?

#2 Galileo Galilei ■Galileo was one of the most ■ influential scientists ever: –Improved the telescope &

made observations about the moon & solar system –Created the Law of Inertia –Perfected the scientific

method ■Galileo’s works challenged long-held

church teachings; He was brought before the Inquisition & forced to recant his ideas

#3 Who’s Scientific Idea?

#3 Isaac Newton ■ Isaac Newton created many scientific

breakthroughs in physics: –Discovered & explained the theory of

gravity –He studied

the physics of motion, light, & heat –Created

calculus to prove his theories

#4 Who’s Scientific Idea?

#4 William Harvey ■William Harvey was an English doctor

who proved that blood circulates through the body & is pumped by the heart

#5 Who’s Scientific Idea?

#5 Andreas Vesalius ■Andreas Vesalius studied human anatomy –His work added to European knowledge

of the human body for first time in more than 1,500 years –Marked the beginning of modern science
